activation: Make sure /etc/sudoers & co. are regular files.
Before that, 'sudo' would exit with:
sudo: /etc/sudoers is not a regular file
sudo: no valid sudoers sources found, quitting
* gnu/build/activation.scm (activate-etc): Check if SOURCE matches
'file-is-directory?'. If not, use 'copy-file' instead of 'symlink'.
